Loudness

Comprehensive Audio and Loudness Processing/Compliance Solutions

Utilizing the Emmy® award-winning loudness processing algorithm developed by Linear Acoustic®, Cobalt offers high-quality loudness processing for baseband signals in our conversion and frame sync cards. Our SpotCheck® Transport Stream Compliance Monitor provides transport-based loudness compliance monitoring/logging for multi-program operators, available in several scalable channel capacity packages.

Here’s a brief overview of audio solutions offered by Cobalt:

  • HD 5.1-channel baseband loudness processing – Cobalt 9985-LP51 – Cobalt +LP Loudness Processing Options (available for numerous Cobalt cards)
  • Stereo SD baseband loudness processing – Cobalt 9085-LP20
  • Audio options available for many Cobalt processing cards:
    +DEC – Decoding of Dolby E/Digital to baseband PCM.
    +ENCDA – Encode PCM to Dolby Digital/Digital Plus with matching dialnorm.
    +ENCDC – Encode PCM to Dolby Digital/Digital Plus (up to four +ENCD encoders can by accommodated on a single Cobalt Fusion3G® card to support multi-language/SAP).
    +LM – Baseband/master control loudness metering works with many Cobalt processing cards in conjunction with our award-winning OGCP-9000 and WinOGCP graphic-display remote control panels.
    +AFO – Automatic audio failover to alternate content sources in absence of a primary source.
    +ADM – Automatic downmix which develops a downmixed stereo source from 5.1 content in absence of a primary source.
    Dolby Transcoding – Cobalt Fusion3G® cards can be ordered with options providing Dolby E decode, processing such as loudness processing and upmixing, and then re-encode to Dolby Digital to provide flexible processing from content providers to emission all in one card
  • Multi-program transport-based loudness complianceSpotCheck® provides easy to use, no-guesswork, automatic A/85 and EBU R128 loudness measurement and access to all audio loudness records. Because SpotCheck® monitors an IP, ASI, or a transmitted over-the-air MPEG stream at the transmit (emission) encode point, SpotCheck® measures and logs loudness for all programming emanating from the facility. SpotCheck® provides easy to read graphical records of spot loudness, and offers configurable e-mail notification to personnel in the event of violations. SpotCheck® is available in several scalable configurations, with records storage up to 1 year.

    LMNTS is a first in comprehensive transport-based loudness processing. LMNTS represents a new level in multi-stream loudness processing integration ease, economy, confidence, and consistency. Operating at the MPEG transport layer, LMNTS provides a practical loudness management solution for MVPD operators without the need or complexity of external codecs transferring between baseband and MPEG interfaces.
